A third suspect has been arrested in the slaying of a 9-year-old boy who was lured from a Chicago playground into an alley with the promise of a juice box and shot to death.

Kevin Edwards was stopped for a traffic violation Saturday in Vermilion County, 150 miles south of Chicago, and arrested on charges of resisting arrest and obstruction of justice. Police say he'll be returned to Chicago, where he faces a first-degree murder charge.

Edwards is suspected in the Nov. 2 killing of Tyshawn Lee. Authorities say Tyshawn's shooting was apparently a gang war killing related to his father, in retaliation for the slaying of the brother of one of the three suspects.

Dwright Boone-Doty and Corey Morgan are already in custody, charged with first-degree murder.
